This command allows you to view a self guided animation of following a path through a 3D surface model. There are two variations to this command. When the command is started, you must specify whether you want to use a surface model from file or screen entities.
Surface model from file: Using this method, you can select either a triangulation (.TIN) file or a grid (.GRD) file, then you have the option of following a polyline or following a "free" path. If you choose the polyline method, then the animation is limited to following the polyline. If you choose the "free" path method, you first specify two points to obtain a starting direction, the while inside the viewer you can point the animation in any direction.
Screen entities: Using this method, you must select a 3D polyline to follow. The animation is limited to following the polyline.
After making the above selections, the 3D graphics window is
opened. The main window is for the animation, the smaller upper
right window shows you the overall plan view, and the smaller
window located at middle right shows you the current elevation,
slope and azimuth. While following a "free" path, you will have a
3rd small window located at lower right which shows you the amount
of roll at your current position.This button raises
the elevation of your viewing position.This button lowers the elevation of your viewing
position.This button turns

to zoom in and out.This
button allows you to rotate the main animation window in any X, Y
or Z direction.This button
allows you to pan.This
